JOSEPH OLIVER JOHN-SON, OF SAN FRANCISCO, CALIFORNIA;

COMBINED GARPET-EEATER AND DUST-PUMP.

Specification of Letters Patent.

Application filed January 11, 1906. Serial No. 295,622.

TooZZ whom it may concern:

Be it known that l, JosEPnOLIvER JOHN- SON, a citizen of the United States, residing at San Francisco, in the county of San Fran- 5 cisoo and State of California, have invented certain new and useful Improvements in a Combined Carpet-Beater and Dust-Pump;

and I do declare the following to be a full, clear, and exact description of the invention,

such as will enable others skilled in the art to which it ap'pertains to make and use the same.

This invention relates to combined carpet heaters and dust urnps. v

The object of t e invention is to provide means whereby a carpet may be whipped or beaten and the dust removed therefrom without detaching the carpet from the floor, and means whereby the dust may be collected and readily disposed of.- Furthermore,

toprovide a machine of this character which may be readily moved over a carpet orother surface to be cleaned andwhich will be light, durable and simple in construction and not liable to become deranged from long-continued use.

' With the above and other objects in View, as will appear as the nature of the invention is better understood, the same consists in the novel construction and combination and arrangernent. of parts of'a combined car et beater and dust pum as will be hereina ter fully described and c aimed.

' In. the accompanying drawings forming part of this specification, and in which like dust box on an enlarged scale.

Referring to the drawin s, 1 designates thepump which consists of a horizontallydisposed cylinder 2, in which is arranged a reciproca'tory piston 3, the rod 4 ofwhich projects througha stufilng-box in one end of the cylinder and has arranged thereon a handle 5. "cylinder are inlet ports 6 and 6 that are adapted to be closed byinwardly-opening Arranged at opposite ends of the" nected the outer ends of discharge pipes '9 andg the inner ends of which are connected to a casing 10, in which is arranged'a ball valve 11.

is secured one end of a pipe 13, the other end of which has connected with it a flexible sec- (ion of pipe 13, the free end of which is chsposed withinza collecting tank or receptacle 14 that contains water to receive the dust and collect it and in which tank is placed a sponge or other porous closure adapted to be kept damp thereby to permit the escape of air but to retain allrlust and foreign .matter.

Connected to the inlet ports 6 and 6 are the upper ends of suction pipes 15 and 16,

the lower ends of which communicate withv a dust box 17. The pipe 15 is directly connected with the top of the dust box adjacent to its forward end, while the pi e 16'is connected with the rear end of the ust box by a flexible section of pipe 18. The dust.box may be of any preferred construction and formed of any suitable material, and is open on its underside and is adapted tohug or contact closely with the car et being cleaned, the sides of the box being s lOWIl in the present instance as tapered at their rear ends.

. Arranged within the box 17 is a vibratory beater, which is here shown, and is preferably, in the form of a fiat bar or plate 19,

which is loosely or flexibly connected at'its rear end to the inner side of and near the top of the rear end of the box above the opening of the pipe 18 by a hinge 27, preferably of leather. The'forward end of the'beater. is fieidbly connected by a strap 20 to the inner side of the forward end of the box, beneath the opening of the pipe 15. In the plate or bar, at a point intermediate its ends, is formed a centrally-disposed aperture 21, that is covered on the up er side of the plate by a leather or other exible cover 22. Connected to the box 17' are upwardly-projecting braces 23, to which are connected handle bars 24. These bars are connected by braces 26? with the pump, and provided with a suitable handle 25, by which the device may be pushed or pulled over the carpet.

or other surface being cleansed. To the Pat-tad. June aiooe,

cylinder, adjacent to its ends are formed discharge ports 8 and 8 with which are con.

In the centerof the valve casing- 18 arranged a discharge opening 12, n which pump is connected a supporting frame 28, in the lower end of which is journaled a roller or die 55 valves '7 and 7 In the underside of the over which the, device'operates.

.Wheel' 26, adapted to'roll-on the floor 'or. car-' pct, as the machine is pushed or pulled over the same. f 1

In the operation of the device, the rear end I of the beater, 19, is held in position above the surface by means of the strap, 27,while the forward end of the beater is adapted to lie in contact with the. carpet, or other surface When the piston is pushed forwardly, the air is exausted from the 16, and the-valve, 7 opens and permits the a t n of the beaten. exhausted from the dust box,

' box by the exhaustion of air .9, to the casing, 10, and thence through the.

pipes, 13'and 15 to a tank, 14:, in which the dust is collected and from which the air is permitted to-escape through the sponge, the all valve, 11, during this movement of the piston being in the positionshown in Fig. 2. Upon movement of the piston in the reverse direction,-the valve, 7*, will be closed'a'nd the valve 7 opened, thereby causing the 'dust which has just been drawn into. the cylinder, to be forced through the port, 8, and pipe, 9*, into the casing, 10, and, at the same time, move the-ball valve, 11, to the opposite end of the casing for closing communication between the latter and the pipe, 9. During :this movementaof the piston, the valve 7 is opened and thesuction created in the pipe,

15, serves to lift the forward end of the beater toward the top of the again swing downwardly into contact wlth the carpet when the piston is again movedbox, 17, through the-pipe,

dust boxin position to The rearward movement of the forwardly.

of course, to exhaust the dust piston serves, from the box, to draw the same into the cylinder, 2.

It will be understood that a ra id manipulation of the piston will cause t 1e beater to vibrate with such speed as to'efi'ect the thorough beating of the carpet for properly cleaning the latter. I I

Having thus described my invention, what I claim as new, and desire to secure by Letters-Patent, is,'-

1. An apparatus of the class described, comprising pump cylinder, an open-bottom dust box, a vibratory beater loosely hung within the latter, suction iipcs connecting the-ends ofthe pump and t e dust box, one of said 'pipes-communicating with. the dust box in a plane below that of the adjacent end of the heater, and the other communicating with the dust box immediately over the other end of the beater, and'a piston operable in the pump cylinder for alternately establishing suction in the suction pi es, thus to effect simultaneously the remova of the dust and the actuation of the beater.

2. .An apparatus of the 1 class described, comprising an open suction pipes connecting the-ends ofthe dust box and the pump, one of said pipes conimunicating with the dust box in a plane below that of the adjacent end of the beater and the other communicating with the dust box immediately over the other end of the beater, and a-dust collecting receptacle communicating with said pump.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit-- nesses. Y
